STARTER - DIRECT DRIVE
1990-92 ELECTRICAL Mazda Starters - Direct Drive
DESCRIPTION
Nippondenso direct drive starter is a conventional 12-volt, 4-pole, brush-type starter. The integral solenoid is
attached to the drive housing. The overrunning clutch pinion drive is mounted directly on armature shaft drive
end.
TROUBLESHOOTING
TESTING (ON VEHICLE)
CIRCUIT TESTING
1. Turn ignition switch to START position, depress clutch and ensure starter operates. If starter does not
operate, use voltmeter to check voltage at "S" terminal when clutch is depressed and ignition is turned to
START position. See Fig. 1
.
2. If voltage is less than 8 volts, check starter interlock switch and ignition switch to starter wiring circuit for
short to ground. If voltage is greater than 8 volts and starter is inoperative, starter has an internal fault.
Repair or replace as required. NOTE: For information on B2200 and Protege models with automatic transmissions,
see STARTERS - GEAR REDUCTION article.
NOTE: See TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL
INFORMATION section.
NOTE: Before testing, ensure battery is fully charged, battery cables and terminals are
clean and tight and engine grounds are good.

Check timing belt for cracks, peeling, abrasion or other damage. Check tensioner bearing for looseness or
roughness of rotation. Inspect tensioner spring for stretching. Replace parts as necessary.
Installation (All Models)
1. Position notch on crankshaft sprocket to 12 o'clock position (aligned with mark on oil pump). Align
timing marks on camshaft sprocket(s). For SOHC, see Fig. 4
. For DOHC, see Fig. 5 or Fig. 7 . Ensure
crankshaft timing mark is at TDC. Install belt around crankshaft sprocket, then working in a
counterclockwise direction, route belt around camshaft sprocket(s).
2. Loosen timing belt tensioner lock bolt, and allow spring to apply tension on belt. Snug tensioner lock
bolt. Rotate crankshaft 2 complete turns in direction of normal engine rotation. Ensure timing marks
align. If timing marks are not aligned, remove belt, realign all timing marks, and repeat installation
procedure.
3. On all engines, check timing belt deflection with 22 lbs. (10 kg) of pressure applied to belt. See Fig. 8
.
Ensure timing belt deflection is within specification. See TIMING BELT DEFLECTION
table. Adjust
drive belts to proper tension.
